i bought a clown loach to help with my snail problem but nothing so far has happened to the little buggers. am i using the right loach? if not whats the name of the one i should use? i have an outbreak of some sort of snail. its not the malaysian snail but right now they look like little brown mystery snails. im not sure how big they get but there messin with my plants and ive already tried the lettuce trick but i think they like my plants better. no chemicals for me so im tryin the loach thingy.
